SHIP PROPULSION.

Specification of Letters Patent.

Patented Nov. 26, 1907.

Application filed December 2l, 1906- Seral No. 348,974.

T o all whom it may concer/n.2

Be it known that I, PAUL HELMUT BELrrZ, a subject of the Emperor ofGermany, residing at No. 26 Lindenstrasse, Stettin, in the Kingdom ofPrussia, Germany, have invented a new and useful Improvement in ShipPropulsion, of which the following is a specification.

The object of the present invention consists of a propelling mechanismfor ships by means of wind motors in pairs fixed upon transverse shafts,said wind motors being supported by means of a iframe forming part ofthe horizontal foot bearing. .l'litherto known constructions of thiskind are provided with a wind motor having only a single wind wheel or aseries of single wheels placed tandem, which however is not suitable forregular ship propulsion because the power obtained thereby is notsufficient for the contnuous propulsion of the ship and moreover thewind wheel is often blown down by reason of the storms occurring at sea.Further the supports of the motor and wind wheel as hitherto devisedwere designed primarily for wind motor constructions on land and werenot adapted for sea requirements. Finally in driving by single windmotors, the dimensions must be very great and consequently theconstruction be attended with much cost and special difficulties. Theobject of my present application is to relnove these drawbacks by theprovision of wind motors acting in pairs upon a single shaft andsuitably supported whereby I am enabled to develop almost double thepower, and in consequence to propel the ship with unich greatereiliciency and certainty.

Referring to the accompanying drawing, Figure 1 shows a longitudinalsection through a ship provided with a pair of wind motors andpropeller' mechanism. Eig. 2 shows the same longitudinal view with thewind motors driving two propellers on separate shafts. Eig. 3 is a planview of Fig. 2. Fig. 4L shows an end elevation of Fig. `Fig. 5 shows apartial end elevation and part section of the vessel with the supportforming the bearing in which the collar holding the vertical shaftrevolves.

The ship provided with one or more pro pellers has set up on it acorrespoiuling number of wind motors. For the purpose of the greaterdevelopment of power two of these motors e and l) are coupled togetherupon the common shaft c. The shaft c 1s supported by the two bearings dand e, the foot ends of which terminate in a common shaft f which servesat the same time as a support for the driving shaft i. This shaft issupported on ball bearings h in the end of the frame g and thisconstruction facilitates an easy adjustment of the wind motors. Thedriving shaft i possesses gear wheels at each end from which the upperwheel 7c takes up the power from the wheel m placed upon the shaft c,while the lower wheel Z transmits the power by means of the wheel o or pto the shaft n located in the ships hold. The further transmission ofthe power to the propeller shafts t and u is effected through the gearwheels fr* s.

The adjusting of the wind wheels or also of the entire set of windmotors is eil'ected by means of any convenient device, which for thepurpose of greater security against damage can be located in theinterior of the vessel and operated from thence.

If more than one pair of motors are placed on one ship, then it isadvisable to arrange them at both sides of the ship, whereby the useofmore than one propeller screw facilitates access thereto and thetransference of the power.

lf it occurs that with my wind motors working in pairs one of the samebecomes out of order, then the second motor can still remain operative,which in the case of the single wind motor known is entirely out of thequestion.

W'hat l claim is:

rPhe combination with a vessel of pairs of wind motors placed side byside, a transverse shaft supporting each pair of motors and revolvedthereby, vertical shafts adapted to transmit motion from the saidtransverse shafts, a plurality of horizontal shafts in operativeconnection with the vertical shafts and a propeller on the end of eachhorizontal shaft.

ln testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

PAUL HELMUT BELITZ.
